Description

Technical Field

[0001] The utility model relates to the technical field of agricultural machinery, in particular to a duckbill transplanter in plant transplanting machinery. Background Art

[0002] At present, the degree of agricultural mechanization is increasing day by day, and agricultural planting and cultivation advocate the integration of agricultural machinery and agronomy. In crop planting, with the addition of transplanters, work efficiency has been greatly improved.

[0003] There are many types of transplanters on the market. The utility model mainly improves the duckbill transplanter. When the duckbill transplanter is working, the duckbill planter performs uniform circular motion around the fixed rotating shaft on the one hand, and performs uniform linear motion as the machine moves forward to plant on the other hand.

[0004] When the duckbill planter is in circular motion, it is in a closed state when it moves to the top (the seedlings will not leak out at this time), and the seedlings are manually placed into the duckbill planter. After the duckbill planter moves to the bottom and inserts into the soil, the duckbill planter opens to plant the seedlings in the soil and moves upward. The above seedling placing and planting actions are cyclically operated to complete the planting operation.

[0005] The existing duckbill planter, when a certain soil moisture is required for planting, is easy to stick to the soil and is not easy to fall off because the duckbill planter needs to be continuously inserted into the soil. The sticky soil causes the seedlings to be blocked by the soil and cannot fall, thereby affecting the transplanting effect of the seedlings. The soil on the duckbill planter needs to be cleaned manually, which reduces work efficiency.

[0006] The design ideas of the utility model are: 1. Through the brush and the corresponding transmission structure, the brush can automatically clean the duckbill planter in the rising stage (open state). 2. With a relatively simple transmission structure, the duckbill planter is always in a vertical state during rotation, and the installation structure of the duckbill planter can be installed with other components that need to keep the angle unchanged during operation.

[0038] When each rotating shaft (rotating shaft) passes through the mounting plate 91, it rotates with the mounting plate 91 through a bearing or a sleeve. This is a conventional technology, and each bearing or sleeve is not described in detail. In the present utility model, the power device of the transplanter is an internal combustion engine (gasoline engine or diesel engine). In the present utility model, each transmission wheel of the comprehensive transmission mechanism is preferably a sprocket, which is used in conjunction with a transmission chain.

[0039] Two tension wheels are provided in the area surrounded by the first transmission wheel 201, the second transmission wheel 205 and the third transmission wheel 202, namely the first tension wheel 203 and the second tension wheel 204. Both tension wheels are pulleys or sprockets and are installed on the back of the mounting plate 91. Both tension wheels are used to apply tension to the integrated transmission chain or integrated transmission belt wound between the first transmission wheel 201, the second transmission wheel 205 and the third transmission wheel 202.

[0040] The tensioner can make the integrated transmission chain or integrated transmission belt have appropriate tension to ensure the stable operation of the transmission mechanism.

[0041] When working, the internal combustion engine of the transplanter drives the transplanter forward, drives the duckbill planter 5 to rotate vertically through the integrated driving wheel and the integrated transmission mechanism, and drives the brush 1 to rotate through the brush driving wheel and the brush transmission wheel 93. When the duckbill planter 5 reaches the lowest point of its vertical rotation trajectory, the planter swing cam 9 presses the planter swing crank arm 12, and the planter swing crank arm 12 pulls the duckbill planter 5 through the first pull wire 6 to open it. Figure 3 The dotted circle in the figure is the vertical rotation track of the duckbill planter 5. Figure 3 The rotation direction of the middle duckbill planter 5 is counterclockwise.

When the duckbill planter 5 reaches the highest point of its vertical rotation trajectory, the operator puts the seedlings into the duckbill planter 5. Figure 3 When the brush is in position B, the brush swing cam 9 presses against the brush swing arm 14, and the brush swing arm 14 pulls the swing plate 92 and the brush 1 below the second pull wire 2 through the second pull wire 2, so that the brush 1 rotates and rises to press the duckbill planter 5. Since the seedling drop-out opening of the duckbill planter 5 is in an open state at this time, some of the long hairs on the surface of the cylindrical brush 1 enter the duckbill planter 5, and some pass through the outer surface of the duckbill planter 5, thereby brushing the inner and outer surfaces of the duckbill planter 5 at the same time, with a good soil cleaning effect, without stopping the machine for manual soil cleaning, and significantly improving the efficiency of transplanting. The duckbill planter 5 arrives Figure 3 When in the middle C position, the protruding portion of the brush swing cam 9 leaves the brush swing arm 14 during rotation, and the second pull wire 2 no longer applies tension to the swing plate 92 and the brush 1. Under the action of gravity, the brush 1 rotates downward and returns to its original position.

[0043] During the forward movement of the transplanter, the rotation of the duckbill planter 5 and the movement of the duckbill planter 5 Figure 3 The opening action from A to C and the brush 1 are Figure 3 The cleaning action from B to C in the middle is coordinated with the duckbill planter 5. Figure 3 When the machine is at the highest position, the action of manually placing the seedlings is repeated, so that the transplanting operation can be continued without stopping the machine for manual soil cleaning, thereby improving the transplanting efficiency.
